I am reclining in a hot tub in the semi-darkness, jets of water below the surface gently massaging my back, legs and stomach while the aroma of peppermint and eucalyptus rises in the steam. As soft music plays, lights change the colour of the water from blue to green to fuchsia pink… Beside me, on the rim of the tub, stands a cocktail, which I reach out for to sip every now and then.
